Darren came, identified what was causing the problem, nipped out to purchase a replacement flush push button, and fitted it, leaving the toilet working as normal. As usual, Darren was very professional and customer-focused. Highly recommended

As usual, an absolutely first class service. The efficiency in terms of fault diagnosis and then coming back to replace the panel having sourced the part in very quick time was excellent. Thank you.

The booking system is easy and it was good to get a specific time for the call out for a boiler problem. Darren diagnosed the issue quickly and provided a quote for the repair work promptly. He was accommodating in returning quickly, and the problem is sorted. He is personable, and I wouldn’t hesitate to recommend him for boiler issues.

Mixer tap installation covered by 'Heat Club' membership
Customer Service
Quality
Value
We pay a monthly 'Heat Club' subscription to Heatco. This covers annual boiler, central heating and gas fire servicing and callout when there's a problem. But it also covers small plumbing jobs – as we were reminded when we needed to replace a leaking mixer tap. We paid for a new tap, but Heatco installed it – quickly and efficiently – without an additional labour charge.

Have been using HeatCo for a few years and found them to be very efficient and extremely trustworthy. Tried other companies (for various things that Heatco doesn't normally do) and have sometimes been quoted several times higher for the same thing or had unnecessary work suggested. Highly recommend!

Darren from HeatCo serviced our boiler again yesterday and as always did a great job. He arrived promptly, with advance warning, and carried out the service with a minimum of disruption. We're very happy to recommend HeatCo to others. The service is great.

Have used Heatco both for individual jobs such as moving rads and also signed up for the annual maintenance plan. The annual maintenance plan covers the boiler servicing and has taken out any worries and associated costs with unexpected problems that inevitably pop up over time on most systems. Individual jobs have always been done on time and competitively. Highly recommend.

I have used HeatCo to service my old boiler and replace it with a new one. They are efficient, courteous and professional. The cost of replacing the boiler was good value. The payment method and invoices were clearly explained and worked well. You also get text messages about their arrival time. Highly recommend.

Boiler Service & Gas Leakage
Customer Service

Darren and colleague arrived ahead of schedule, and in addition to carrying out a Boiler Service, also performed numerous tests to trace a minor Gas Leak revealed beforehand when a new Smart Meter had been installed by my energy company. Eventually the problem was resolved by capping supplies to a couple of unused gas appliances. Excellent detective work and prompt service at a very reasonable cost.

Excellent service from Shaun at HeatCo who fixed 2 plumbing issues. One was fitting a new plug to the the sink and the other was a new Geberit flush valve to the toilet. The work was easy to schedule with the online booking system and the appointment was kept on time. Work was performed efficiently and very professionally and ai would definitely recommend

Old boiler with intermittent fault
Customer Service

I originally booked HeatCo to attend because the boiler had failed. However, after not working for 24 hours the boiler came back on of its own accord. I asked HeatCo to attend anyway to check that the boiler was safe to use. The engineer checked the boiler over and gave it a clean bill of health. They suggested that we consider changing the boiler since it is nearly thirty years old but there was no pressure to do so.

Shaun fixed a leak in my house really quickly and efficiently. First, he turns up on time, acts respectfully in my home towards me, my wife and my kids. He quickly assesses the problem and then clearly explains to me what he needs to do and then gets on and does it. With all the kids off for half term it was carnage in the house with them being noisy, Shaun just got on with the job like a pro. Thanks, Shaun
